STARS JACOB W. MUELLER, OF MILLSIADT, ILLINOIS.

SHOCK-LOADER.

To all whom it 'may concern:

Be it known that I, JACOB W. MUELLER, a citizen of the United States,and resident of Millstadt, Illinois, have invented certain new anduseful Improvements in Shock-Loaders, of which the following is aspecification.

This invention relates to improvements in shock loaders and consists inthe novel arrangement, construction and combination of parts as will befully hereinafter described and claimed.

The object of my invention is to construct a shock loader to be attachedto the rear end of a vehicle whereby the shocks of wheat and the likemay be picked up during the movement of the vehicle and automaticallyconveyed into the vehicle.

Figure 1 is a top plan view of my invention showing it in position onthe rear end of a vehicle. Fig. 2 is a front View of the same showing avehicle body in section. Fig. 3 is a detail top plan view of the gearand clutch mechanism by which the shock carrying frame is manipulated.Fig. 4 is a detail perspective view of the rollers and portion of frameby which the shock carrying frame is conveyed on the track. Fig. 5 is adetail perspective view of the inclined dog carried by the frame bywhich the clutch mechanism is operated. Fig. 6 is a detail perspectiveview of one of the clutch operating pawls carried bv the sprocket chain.Fig. 7 is a detail perspective view of a portion of the rail on whichthe shock carrier operates and the standard supporting the same.

In the construction of my invention, I provide a pair of standards 8which are rigidly attached to the body 9 of the vehicle, the saidstandards extending upwardly at a sufficient height so as not tointerfere with the loading of the body and on the upper ends of saidstandards are rigidly attached guide rails 10 on which the shock frame11 operates.

The shock frame 11 consists of a'rectangular frame 12 supported onhorizontal cross bars 13, the ends of said cross-bars provided withrollers 14 which are designed to come in contact with the inner andouter surfaces of the rails 10. The ends of the cross-bars 12 areslotted and in said slots are pivotally mounted rollers 16 which arearranged to contact with the inner edge of the rails 10 so Specificationof Letters Patent.

I as to prevent binding yet permit the shock frame to freely operate andtravel on the rails.

The rails 10 after passing from the standards 8 are bent downwardly, seeFig. 2, and suitably curved at the point indicated by the numeral 17,the bottom ends of said rails bent abruptly as indicated by the numeral18 forming a stop to limit the downward movement of the shock frame. Inthe frame 12 is held a shaft 19 and on said shaft is supported aplurality of sleeves 20, each sleeve supporting prongs 2l of suitablematerial and bent to accommodate the encircling of a shock of wheat orthe like; each alternate prong extending in opposite directions. Theseveral prongs forming each frame are rigidly connected together by therod 23 and to said rod is attached a cable 24 by which said prongs areoperated when drawn up so as to encircle the shock and retain the Samebetween the prongs. The opposite end of the cable 24: is attached to anarm 25 which is pivotally mounted at the point indicated by the numeral26 to an upright 27 forming part of the frame, the opposite end beingattached to the sprocket chain 2S.

On the frame 12 and centrally located is a curved pivoted arm 29 whichextends outwardly and between the prongs 21 so as to come in contactwith the shock and manipulate the clutch mechanism hereinafter describedby means of the projecting arm 30 forming part of said lever coming incontact with the clutch arm 31.

The bottom of the frame 12 is provided with a shoe 32 constructed ofsome resilient material, said shoe supporting the frame above the groundand preventing said frame from contacting with projections and to keepthe lowest series of prongs a suitable distance above the bottom of theshock so that said prongs have freedom to operate.

The clutch operating mechanism consists of a short shaft 33 supported inbearings 34 which are attached to the side of the vehicle body and onsaid shaft is mounted a sleeve on which is mounted bevel gears 35 and36. Intermediate of said gears and upon said sleeve is loosely mounted asleeve 37 to which is attached the clutch operating arm 31. The sleeveon which the bevel gears 35 and 36 are located, is keyed upon the shaft33 in such a manner as to permit the same together neath the bevelgears, I provide the bracket' 45 on which is pivotally mounted at thepoint indicated by the numeral 45 a clutch operating lever 47, thepurpose of which will be hereinafter described.

On the short shaft 33 and to one side of the-bevel gear 36 is keyed asprocket wheel 48 by which the sprocket chain 28 is placed in operation,said sprocket chain being of an endless type and is passed over sprocketwheels. 49, 50 and 5l supported by the uprights 8, and in such aposition as to permit the shock frame to ride upon the track l0 whichmovement is imparted by the endless sprocket chain 28.

On the standards 8 and in front of the rails 10 is pivotally mounted ashaft 52 which is provided with a plurality of projecting arms 53suitably bent, and saidshaft is placed in revolution by the sprocketchain 54 operated from the traction wheels 44. The object of this shaftis to contact with the shock after it has been released from the prongsof the shock frame and cast the shock from the table 55 on which it ispermitted to fall and deliver said shock into the vehicle body. Upon theshafts supporting the sprocket wheels 49 and 50, I provide sheave'wheels56 over which is passed a cable 57, its one end attached to the shockframe, the opposite end provided with a counterbalance weight 58. Thepurpose of this is to counterbalance the weight of the frame togetherwith the shock when the same is being raised from its lowest verticalposition to its highest horizontal position.

The sprocket chain 28 is provided with a pawl 59 and is so arranged asto come in contact with the clutch operating arm 47 at a proper period,manipulating the operating clutch, reversing the operating mechanism.

The clutch frame is also provided with a dog 60 having an inclinedsurface 61 which is so placed and arranged as to contact with the end ofthe clutch arm 31 when the frame has reached its lowest point, placingboth bevel gears 35 and 36 out of mesh with the bevel gear 38,permitting the frame to remain idle until it has been brought in contactwith another shock.

lThe operation of my invention is as follows: My device, comprising ashock elevating mechanism, can be attached to the rear end of a vehicle;the shock carrying frame being placed in the position as shown 'the'shock.

in Fig. 2 and as the vehicle is being propelled forwardly, the shockfirst coming in contact with the arm 29 manipulating the clutch throwingthe bevel gear 36 in mesh with the bevel gear 88 which is at all timesin operation. At this period the chain 28 is being operated and by meansof said chain being attached to the end of the pivoted arm 25, the cable24 is drawn up which in turn closes the prongs permitting them toencircle Then sufficient tension has Ybeen brought upon the. shock andby means `of the continuous operation of the chain 28, the frame 12together with the shock is conveyed upwardly bringing the shock in ahorizon-tal position on the rails l() and when the frame togetherwith'the shock has been elevated on the horizontal sections of therails, the pawl 59 carried by the chain contacts .with the arm 47thereby placing the clutch mechanism in reversed position, bringing thebevel gear 35 in contact with the bevel gear 38, reversing the movementof the chain 28. At this period of change, the prongs are permitted bymeans of the weight of the shock to open and the shock is permitted toroll on the table 55 and is cast from said table by the prongs 53 of theshaft 52. The shock frame in this condition, is permitted by thereversed movement of the chain to lower itself and when the shoe-'32contacts with the ground, the tapered dogv 60' carried by saidVframe,rcontacts with the arm 8l operating the clutch in such a manneras to release both bevel gears 35 and 36 from the bevel gear 38discontinuing theY operation until the next shock has contacted with thearm 29 when the operation as previously described is repeated.

Having fully described my invention, what I claim is:

l. A shock loader comprising a shock supporting frame; rails supportedto a vehiclebody; prongs carried by the shock lifting frame forcontacting with the shock and supporting the same; a clutch mechanismfor operating the shock lifting frame and a means for automaticallyplacing the shock lifting frame in operation bythe contacting of theshock, and means-for reversing the 1`l5 movement after the shock hasbeen delivered, substantially as specified.
